Strawberry is a perennial herb belonging to the genus Rosaceae. Its fruit is soft, juicy, sweet and sour, rich in protein, vitamins, and minerals. It is a popular fruit. Practice has proved that strengthening spring management, disease prevention and pest management is the key to promoting strawberry ripening and increasing yield.
Unmasking
When the average daily temperature stabilizes at about 10°C, the cover of the cold is removed and it is removed in late March. However, attention should be paid to combining the work of hardening seedlings to gradually adapt to the external environment so as to prevent the temperature difference from being too large and affecting its growth and development.
Cut off old leaves
After cutting into the cultivator in spring, the old leaves are cut off. After the start of growth, the dried old leaves and diseased leaves were cut off in time to improve the ventilation and light conditions of the plants and reduce the humidity in the fields. The residual leaves removed from the field should be taken out of the field and concentrated on the stacking of fertilizers to eliminate various pathogenic bacteria and prevent the spread of pathogens.
Pest control
The soil pests that damage strawberries in spring are earthworms, ground tigers, and golden needles, which mainly damage the roots and stems of strawberries. The following prevention measures can be taken:
The first is to carry out shallow worms, which can effectively eliminate eggs and larvae on weeds and soil.
The second is to artificially excavate the ground tigers and slugs and kill them near the affected strains.
The third is to use 90% crystal trichlorfon 200 grams or 50% phoxim emulsion 200-300 grams per acre, 500 kilograms of water, watering the roots, or sprinkle poison bait prevention. Poison bait preparation method: use 90% crystal trichlorfon 50 grams, 1 to 1.5 kilograms of water, stir fry 2.5 kilograms of wheat bran, or stir in 10 kilograms of chopped fresh grass, can be applied.
Disease prevention and control
The main diseases of strawberry are brown spot, gray mold, powdery mildew, virus disease and so on.
With 2% agricultural anti-120 water 200 times, or 50% thiophanate 500 to 1000 times spray control brown spot.
The gray mold was sprayed with 50% nongrilled WP 800 times or 50% quick WP wettable powder 1000 times.
The powdery mildew was sprayed with 12.5% ​​of myclobutanil 2000 times or 20% triadimefon WP 1000 times.
The most fundamental measure for the prevention and treatment of viral diseases is the use of virus-free vaccines and the prevention and transmission of aphids. At the same time, they can be sprayed with 1.5% of the diseased plant disease emulsion 1000 times or 83% of the agent 100 times. With 50% anti-inflamy WP 2000 times, or 10% imidacloprid wettable powder 1500 ~ 2000 times spray, control insect transmission of insect aphids, which can reduce the incidence of viral diseases, but also the concurrent management of oysters, oysters and other underground Pests.
